In the drawings, in which similar reference characters designate corresponding parts. Y

Figure 1 is a side elevation, partly in section and partly broken away, of a column and girders connected by the interlocking joint. Y A

Figure 2 is a similar view, showing the side at right angles to that shown in Fig. 1.

Figure 3 is a horizontal section on the line l3 3 of Fig. 2.

Y Figure 11 is a horizontal section on the line LLP-et of Fig. 1.l v- Figures 'and 6 are detail perspective views lshowing the ,ends of the girders.

Figure 7 is a detail perspective view showing the upper end of the lower column section.

Figure 8 is a similar view showing the lower end of the upper column section.

l Referring to the drawings in detail, 10 and 11 respectively designate upper and lower sections of a column rectangular in cross-area. Each of these sections is of H- shape formation. The sides of-the upper section between the flange edges are closed by the opposite face plates 12 secured to the edges of the flanges. The sides of the lower section between the flange edges are closed by the opposite face plates 13 secured between the edges of the flanges. The face plates 12 and 13 are secured in place by bolts, as indicated on the drawings, but it is obvious that they can be economically welded to the flanges by the electric welding apparatus now coming into general use for extensive operations of this character. The face plates not only strengthen the column sections, but also serve to impart a box-like formation to the same. The face plates 13 and the web 14 of the lower section are cut away to provide a transverse recess between the flange'sides at the upper end of the lower section, the upperfedges of the web and cut away face plates being in the same transverse plane. The upper parts of the flanged sides of the lower' section are slotted, as at`15, in the plane of the web 14. The web 1G of the upper section and the face plates 12 are cut away at thel lower part of said section to provide a transverse recess between the flange sides, the lower edges of the web '1G and the opposite faceplates 12 being inthe same plane normal to the longi-v tudinal axis .of the section. In assembling the column parts, the recessed ends of the sections are fitted together with the flange tively abutting the end edges of the'plates 12 and So assembled, the'wehs of the two sections are normal vto each other, Abut spaced apart and the flange sides of the up-` shapeand'the latter ofv H-shape. The gird-V ers 19 extendV in horizontal alinement from the flange sides of the lowersection 11 in opposite directions. Likewise, the girders 20 extend from the opposite flange sides of the upper column section 10' and at right angles to the girders 19. The upper and lower fiangeson each side of the girders 19 are notched, as at 21, so that the girders can be fitted into the slotsl of the lower seetion 11, Also, the upper and lower flanges on each side of the girders 2O are notched, as at 22, so that these girders can be fitted into the slots 17 of the upper section 10. The width of the girders 20is th'e saine as the width of the flange sides with which they are engaged and this width is the saine as the space between the flanged sides of the lower sectionll. The width of the girders 19 is less than that of the girders 20and the ends of the former fit between the ends of the latter.

The inner ends of both pairs of girders are shaped to fit in interspaced vrelation to each other and between the Vupper edge of the web 11i and the lower edge of the web 16. vThe upper surfaceswof the girders 19 are flush with each other and with the upper edges of sides interspaced and their end edges respecthe flange sides of the lower section 11. On these upper edges are seated the lower edges of the face-plates l2 of theupper section and these plates also seated on thel upper faces of the girders 19 hold the latter against any tendency that the girders might have t0 move upward in the slots 15. rlhe under surfaces of the girders 20 are flush with the lower edges of the flange sides of the upper section l0 of the column and these lower edges are seated on the upper edges of the face plates 13 of the lower section of the column. 'Ihe'girders 2O are also seated, between the lower slots 22, on the upper edge of the face plates 13 and thereby the load of these girders is sustained.

By the foregoing construction an interlocking point is `provided between the upper and lower vcolumn sections and between the ends of the girders. The parts can be quickly assembled in engaged relation without the use of bolts or rivets and the joined parts are securely heid against displacement.

What I claim is: i

l. In an interlocking joint for metallic frames, the combination with a column formed of' upper and lower sections of vH- shape, each section having an end with the web removed between the flange sides and said sides having slots therein in the Ysame plane as the web of the section, said sections being interlitted with the ends of the flange sides of' one section `seated between similar ends oi the other section and with the webs of the two sections normal to each other, and flanged gil-ders seated in the slots inthe ends of the column sections, the flanges of said girders being notched for theinsertion of the flange sides of the columnsections.

"2. In an interlocking joint for metallic frames, the combination with a column formed of' upper and lower sections of H- shape, face plates closing the open' sides of the two sections, each section having an end with the web and face plates removed between the ends of the flange sides, the flange sides of each section having slots therein in the same plane as the web of the section, said sections being interfitted with the ends of the flange sides ofl one section seated between similar ends of the other section and the flange sides of' one section abutting the face plates closing the sides of the other section, and flanged girders seated in the slots in the ends of the column sections, theflanges of said gir-ders being notched for the insertion of the flange sides of the column sections.

3. In an interlocking joint for metallic frames, the combination with a column formed of'upper and lower sections of' ,H- shape, face plates closing the open sides of the two sections, each section having an end with the web and face plates removed' between the ends of' the flange sides, the flange sides of' each section having slots therein in the same plane as the web of the section,

said upper and lower sections being inter@ fitted with the ends of' the flange sides of one section seated between similar ends of the other section and the flange sides of' one section abutting the face plates closing the sides of the other section, and flanged girders seated in the slots inntheflange sides ofthe column sections, each girder having a top or bottom surface flush with the edge of the flange side in which the girder is seated and each girder contacting with the edge of the closing'face plate abutting the flange side in which the girder is seated, the flanges of' said girders being notched for the insertion of the flange sides of the column sections.

In testimony whereofI affixvmy signature.
